Washington DC (US), Aug 27 (ANI): President of the United States Joe Biden after the Kabul blasts said that there has been no evidence of collusion between Taliban and Islamic State. “We are able to leave on time. As a consequence of that, we have asked them to give more space between the wall, stopping vehicles coming through etc. It is not what you called tightly commanded regiment operation like the US is militaries but they are acting in their interest. So, it’s not matter of trust but a matter of mutual self interest. But there is no evidence thus far that there has been a collusion between Taliban and Islamic State in carrying out what happened in front of the hotel and what is expected to continue beyond today,” said Biden.
